Hi
jkjsadkjadksj,
Thank you for your post. For schools like CBS and INSEAD, one of the first steps toward improvement is to raise your GMAT score. As an Indian male engineer, you are applying from the most crowded and competitive demographic. Against that backdrop, I would normally say that applicants with extremely strong profiles and extremely strong application execution (essays, etc.) should target a 740+ as a baseline (a 740 certainly does not win you admission... you still need to win the application war after that... but right now, a 710 has you out of range of CBS and INSEAD).
That said, if your GPA is low (and if you don't have any real extra-professional leadership or super-unique experiences, you will have ground to make up, so you may need to target 760+. Short of all of that, you would need to recalibrate your school strategy. And even if you were to hit those marks on the GMAT, you should almost certainly still consider diversifying your school strategy anyway, as it's quite aggressive / top-heavy right now (see links below).
NUS isn't as competitive on the GMAT front, but there are still tons of applicants from your pool with super competitive profiles scores, so you should raise yours. Beyond the exam, there's not much detail listed, but you'll need to show all of these schools the impact, progression, and unique experiences you've had at your job; the community engagement and habits of leadership that you've demonstrated through extraprofessional activities outside of work (if you don't have any, then you'll need to develop in this area, which might lend itself to applying next year rather than this year); super specific, well reasoned, logical and coherent career goals (see link below); a multi-layered and super specific rationale for why you need an MBA; a deep understanding of each school, its offerings, its culture, why you fit, and how exactly you'd uniquely contribute; very strong, very specific, evidence- supported recommendations; and much, much more. In short, you need to have an *excellent profile* and *excellent applications and essays.*
Here are few links that I encourage you read through to gain a better understanding of the admissions landscape:
